Vulnerability Details CVEID: CVE-2016-0763 DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by an error in the ResourceLinkFactory.setGlobalContext() method. By injecting malicious content, an attacker could exploit this vulnerability to read and write arbitrary data. CVSS Base Score: 6.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110858 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) CVEID: CVE-2015-5345 DESCRIPTION: Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by an error when accessing a protected directory. By redirecting to the URL, an attacker could exploit this vulnerability to determine the presence of a directory. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110857 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2015-5346 DESCRIPTION: Apache Tomcat could allow a remote attacker to hijack a valid user's session, caused by the failure to recycle the requestedSessionSSL field when recycling the Request object to use for a new request. By persuading a victim to visit a specially-crafted link and log into the application, a remote attacker could exploit this vulnerability to hijack another user's account and possibly launch further attacks on the system. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110854 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) CVEID: CVE-2015-5351 DESCRIPTION: Apache Tomcat is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input by the index page. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to perform unauthorized actions. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities. CVSS Base Score: 8.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110859 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) CVEID: CVE-2016-0706 DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by the loading of the StatusManagerServlet during the configuration of a security manager. An attacker could exploit this vulnerability to obtain deployed applications and other sensitive information. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110855 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2016-0714 DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by an error in multiple session persistence mechanisms. By placing a malicious object into a session, an attacker could exploit this vulnerability to bypass a security manager and possibly execute arbitrary code on the system. CVSS Base Score: 7.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110856 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) Affected Products and Versions 6.2.1.0 Remediation/Fixes Product VRMF Remediation/First Fix IBM UrbanCode Release 6.2.1.0 6.2.1.1 Get Notified about Future Security Bulletins Subscribe to My Notifications to be notified of important product support alerts like this.
